Abstract
PURPOSE: To obtain higher deodorization effect by treating offensive odor gas of sulfide series with an alkaline washing liquor containing ozone and powdered active carbon.
CONSTITUTION: Offensive odor gas of the sulfide series, e.g., hydrogen sulfide, etc., is sent through the air blower 1 to the washing tower 2, where the gas is oxidized by ozone from the ozonizer 3 at the first stage of the washing tower 2, and then the gas so oxidized is washed with the powdered active carbon suspension 13, prepared mixing the alkali 7 with powdered active carbon and water, and then with the supplmentary water 8 to remove acid offensive odor substances and their reaction products. And, the active carbon-containing alkaline washing liquor is discharged through the overflow pipe 6 into the sedimentation tank 12 where the active carbon is separated. With such a treatment method, offensive odor gas can be treated with higher deodorization effect than with the washing liquor containing alkali alone.
